I bought the engine degreaser and followed instructions. I have a 2001 maxima. I let it sit with engine cold for 15 min the sprayed off with garden hose, let car warm up and dry engine off, then used the engine shine as directed. Car ran fine the next morning, but this evening my wife drove it 5 miles and cut it off and won't fire now. I checked all fuses and sprayed starter fluid in while cranking. I'm pretty sure I'm not getting a spark. Any and all suggestions appreciated. Thanks, Nathan
